Fix edge and node labels disappearing at middle zoom levels

[tmchow]

Summary

Set minZoomedFontSize to 0 in both defaultEdgeStyle.ts and defaultNodeStyle.ts. The previous value of 6 interacted with fontSize: 7 to create a narrow band at intermediate zoom levels where Cytoscape.js would hide labels unexpectedly.

Changes

• packages/graph-explorer/src/components/Graph/styles/defaultEdgeStyle.ts -- minZoomedFontSize: 6 to 0
• packages/graph-explorer/src/components/Graph/styles/defaultNodeStyle.ts -- minZoomedFontSize: 6 to 0

Setting minZoomedFontSize to 0 disables the zoom threshold entirely, so labels stay visible at all zoom levels until they're naturally too small to render. This matches the expected behavior described in the issue.

Testing

Verified the change is scoped to only the two style files referenced in the issue. The Cytoscape.js min-zoomed-font-size property at 0 means "always show the label" per the Cytoscape docs.

Thanks @tmchow for the submission. I'll take a look soon.

@tmchow I'm closing this since I couldn't reproduce the original issue, and I created it. Maybe it was a total fluke occurrence.

Let me know if you saw the behavior when you fixed it. And try the latest code on main to see if the issue still exists. If it does, we can re-open this. But i don't want to merge the change unless it is necessary.
